The Nitecore Halo 10 Titanium Measuring Ring is a precision instrument designed for measuring curved and irregular surfaces with exceptional accuracy. Crafted from high-grade titanium alloy using precise CNC machining, this measuring tool features a built-in high-quality bearing that ensures smooth rotation during measurement operations. With dimensions similar to a standard coin and weighing only 26 grams, the ring offers portability and can be comfortably worn around the neck using the included lanyard. The measuring ring incorporates clear numerical markings where each complete rotation corresponds to 10 cm of measurement. To use, simply reset the reading to zero, align the ring vertically with the starting point of the measurement surface, and roll it along the path. An audible click indicates the completion of each full rotation, allowing users to obtain measurement results by counting rotations or reading the numerical indicators directly. The titanium construction provides durability and corrosion resistance, while the smooth, rounded finish ensures comfortable handling during extended use. This measuring tool is suitable for various applications requiring precise curvature measurements and dimensional analysis of irregular surfaces.
